This selector isn't a good idea - CMMG, Inc Ambidextrous Safety Selector Kit

I bought this selector because it was inexpensive and it seemed like a good idea to have an ambidextrous option on my rifle (I'm not highly experienced with building weapons and I don't get a ton of range time). However for another rifle I purchased a short throw ambidextrous selector and having used both I understand completely the purposeful design of the short-throw option. With this symmetrical selector on my right hand the length of the lever interferes with my hand placement when I hold the pistol grip. That is slightly uncomfortable for short use but could be irritating or even blistering if I were to be shooting all day without gloves. I suggest you either go with a standard safety selector or decide to spend a bit more money and purchase an ambidextrous selector that has a short throw on the right side of the rifle. With all of that said this selector operates fine. It isn't manufactured poorly and the finish is nice too.
